I'm personally looking forward to the day when our phones eliminate cluttered collections of credit cards, receipts, business cards, and cash stowed away into already overstuffed wallets. Actually...you can do it now! The Lemon Wallet app allows users to digitize copies of an assortment of identification and payment cards – ID, insurance, loyalty and credit cards – for use and safe keeping. Everything is encrypted, with a security PIN required to access/use the virtual counterparts of your wallet (if you lose your phone, you can remotely unlink it from your account from your computer), with the ability to photograph and store receipts right from the app for easier budgeting. The question is, who amongst us is courageous enough to ditch the wallet altogether?
